To all whom it may concern:

Be it known thatI, WALTER Willem, a citizen of the United States, residing in New York, inthe county' of New York and State of New York, have invented certain new and useful Improvements in Loinbined Type-(ritin and oo mpntiii ,Machines, of which the fofiowing is n specification. 4

This invention relates .to coinp 'ljti'ng inachines of the class shown iii thnpclnling application No. 643,603, of Wright and a constantly revolving power shaft iseaused to assistat' the operat onpficarrying. tens power sha ftmt the'itens-jmr' mg operation-,T

According to the present, ilnln'ovoinonts, a rolling device (prefitralily a pinion) is employed to transmit. inovonicnt from the constantly rotating nltllll tl' to the livo-Iolu-d wheel aforesaid. said pinion being caused to mosh with tooth 'l'ornwd upon the onds.'of

[This shaft- 22 carries at its upper end a inion 23, meshl-iorizontal shaft .25, to which is fixed-n mnst'er'wh'eel 26, hnving 'oppi' site teeth :27 to engage interior notches :28 in a gaug'of computing wheels 29;. said gang mounted on .a carriage 30, Much travels on rails 31, 32, and is conncdad hyan arm 33 to the carriage 34 of the t vpewriting machine; said carriage 34 having a platen 35.:rgainst the fron of \\'liieli strikc types 36: and said carriagealso having a rack 37 meshing with apinionBS connected to an osmpement wheel 39,-which is controilqdhv |(t \'-0plltll0 (1 dogs 40, 41.

'lho computing wheelslfl'mosh with-gears 30 provided upon nunilwr-henring wheels 31. All of the foregoiugparts are set forth in said pending application, and form no part of the present invention.

Each (-omputing'whecl 29 is provided with a tons-carrying tooth 4:2. which. once in each revolution of said wheel, strikes one of the live teeth 43 of a revoluble wheel 44, thereby starting or performing a portion of the tens-carrying operation. t On this wheel 44 is fixed pinion 45, which meshes with the computing wheel- 29 of next higher denomination, so that when said five-toothed wheel 44 is rotated one-fifth of a revolution, the next higher computing wheel is rotatedone-tenth of a. revolution, thus adding oneron the higher wheel. ..I r

The present invention relates to the auxiliary tens-carrying mechanism, that is;-the means whereby-the tens-carrying operation is assisted or largely performed. This mechanism includes a five-lobed wheL-that maybe locatedbetween thewh'eel 44 and pinion 45, and fixed to both thereof. Be-' tween the lobes 46 0f this middle wheel are formed depressions or notches 47, engageable 'by a. yieldingdetle'nt' 48, in the form of a. roll or wheel provided upon thelend' of an arm 49.- and pressed bye spri g .5 into the notch-47; 7

- The detent 48 isprovided'upon its periph-- ery with fine teeth 'or serrations, which perform a special function at the tens-carrying operation, without detractin from-the usefulness of the wheel as'a etent. Duringv that portion of the revolution. of the five-1 lobed wheel 46, which is efi'ectedi'by the tens-" carrying tooth 42, the serrations or teeth 51- formed upon the adjoining lobe 46 come into mesh with the 'serrationson the detain-48; the latter yieldin at. the rotation inf-the lobed-wheel 46, an riding upon the endpf said lobe, as will be understood b reference to Fig. 4. This backward yielding move. ment of the wheel 48 not only brings it intomesh with said teeth'a'il, but'also brings sai'd wheel 48 into mesh with a 'pinion..,52 fixed on' a constantly revolving shaft 52', which th us serves as an auxiliary driver for assisting or completing the tens-carrying operation).

This pinion- 52 (of which there is one for each lobed wheel 46) is moving at high speed in the same rotary direction as the lobed-wheel 46, and the wheel .48, upon meshing with 52, therefore serves to Iran: mlt movement from 52 to 46, thcreby'eomplcti'igfi the motion of the lobml-wheel 46. as

well as of the pinion 45; .while the whet-1 48.- snaps bodily into the next recess or notch 47 in the lobed whorl, thereby not only becoming disconnected from the barrel pinion 52, but also properly positioning the whet-156;- ete., and the computing wheel 29 of next higher denomination.

The assisting shaft 52 is kept in constant rotation by means ofthe electric motor .1; the connection including a pinion 53 on the shaft of the motor, a pinion 54 in mesh tliermvitli, a pinion 55, bevel pinions 56 and 57, shaft 58, livrcl pinions 5!), 60, shaft 61, bevel pinions 62, 63, shaft 64, pinions 65, 66,

shaft-67, and pinion 67 thereon meshing with pinion 52" onshaft 52'.

It'w'ill be seen that so long as the inter-- ponent 48 can be moved by the lobes 46 into contact with the. constantly revolving driver 70 -52, so as to serve as'a movement-transmitter bet-ween 52 and 46, it is not essential in all casesthat the teeth or serrations be provided upon all-'or' any of these members,

since the member-52 might be inthe form of a smooth soft-rubber cy nder; as illustrated in certain of my other-pending applications; and other variations-may be resorted to within the :scope-of this portion of the invention. In the presence instance, the carriage 30 contains a lof the computin wheels 29 and the number "wheels -30,' "an carries them bodily stepby-lstep to accompany the move- .ments of'ithe-carriagei-ofthe typewriter, 35

while the-master. wheel 26 does not travel; and it. results that the'computingwheels 29 arev presentedtisuccessively; to" the master hee ,to beo'pemted therebyf r U. ntheeonstantly revolving shaft 64 is pinion 65', meshingwithja pinion 66,- the latter' sjilined-orfittediupon a'square shaft-67,,which is movable endwisewith the eomputin'gfcarriagew; said shaft having at its ends b0$508-68 journaled by ball bearings. in .nrm 69 of; snid carriage- 30.
